2023 Keystone Cougar 368MBI Parts Needed for Pin Box Upgrade to Reese Sidewinder  


I have a Lippert 1621 king pin on my 2023 Keystone Cougar 368MBI. It has a gvwr of roughly 14000 lbs. Is the 16000 lb 5th airboure sidewinder sufficient for my trailer? Is their a heavier 5th airboure sidewinder available?


Helpful Expert Reply:

Yes, the 16K 5th Airborne Premium 5th Wheel Air Ride King Pin with Sidewinder # 5AS16K will be perfect for your 14K 2023 Keystone Cougar 368MBI.

Please note you also need the rotating turret part RP61300. This is currently unavailable so you'll want to search elsewhere to see if you can pick up this specific part even if it's used.
